■ Performance Characteristics

■ Power Derating Curve

Power rating or current rating is in the case based on continuous full-load at ambient temperature of 70℃.

For operation at ambient temperature in excess of 70℃, the load should be derated in accordance with figure

of derating Curve.

■ Voltage Rating or Current Rating

Resistance Range: ≧1Ω

Rated Voltage: The resistor shall have a DC continuous working voltage or a RMS AC continuous working

voltage at commercial-line frequency and wave form corresponding to the power rating, as determined formula

as following:

E=Rated voltage(V)

E=√P×R P=Power rating(W) R=Nominal resistance(Ω)

■ Equipments Applicable:

Our company’s products are produced under low temperature processing applicable to IR reflow surface mounting

devices. It is comparatively not applicable to wave soldering which will possibly cause the risk ablating the element

protection layer and the front conductor and cause the drift of the resistance value and ablation of the markings.

■ Product Testing Method:

Our products are tested with our company’s tapping & testing equipments by using four-feet probe to touch at the back of

both electrodes. Supposed different testing points or methods are requested, please advise beforehand and

customized-made production is available.
